Special Radio Features
 
Dynamic Regrouping
 
The dynamic regrouping feature allows the dispatcher to temporarily 
reassign selected radios to a single special channel so that they can 
communicate with each other. This feature, enabled in each radio by means 
of the radio service software, is typically used during special operations. You 
will not notice whether your radio has this feature enabled until a dynamic 
regrouping command is sent by the dispatcher.
If you select the dynamic-regrouping zone/channel using 
softkeys or other radio controls without being dynamically 
regrouped, an invalid tone will be heard.
1. When your radio has been dynamically regrouped, you will hear a 
“gurgle” tone (unless you are already on the dynamic-regrouping 
zone/channel), and your radio will be automatically switched to the 
dynamic-regrouping channel. The display will show the name 
assigned to the dynamic-regrouping channel.
If you are using a radio control knob or switch (not softkeys) to 
select the zone or channel — Until you select the correct 
dynamic-regrouping position, you will not be able to select 
scan, telephone call, or Private Conversation call feature, and 
you will hear a gurgle tone each time you press the 
 
PTT Switch
 
. 
This is a reminder to you that you are transmitting on the 
dynamic-regrouping channel, not the zone or channel 
indicated by the position of the radio control.
If your radio is programmed as a 
select-enabled radio: Once you 
select the correct dynamic-regrouping position, you can 
change the radio’s zone or channel knob/switch position, press 
the 
 
PTT Switch
 
, which will transmit on the dynamic-
regrouping zone/channel, and you will not hear the “gurgle” 
tone.
